Permit you to monitor your network with real-time status of all links and nodes. Color coding indicates current status green is normal condition, yellow reflects a deteriorating condition, and red represents a critical problem. Alarm threshold parameters are established by the operator.
When an alarm condition occurs, the affected link (or node) turns red. Also, an audible alarm sounds further helping to notify the operator, regardless of which screen is being displaying when the alarm occurs. When a problem arises, you are the first to know.
In this mode, both the maximum number of errors on inbound and outbound data paths, as well as the maximum internodal delay time can be set easily using the menu instructions. Error thresholds can be established for each configured device in a node to meet the needs of the network manager.
This display includes a seven-dot event report for each device. Each dot represents a critical operations parameter, such as remote node initialization, line outage, buffer status, node congestion, and more. If the device is operating normally, all seven dots are green. If a problem occurs, the appropriate dot turns red. This allows the operator to isolate a problem more quickly.
After initiating a loopback, a test character can be sent through the system toward an end point selected by the operator. If the test character is received at the originating node without error, the channel path is displayed as "green" and the delay time displayed in the lower right-hand corner of the ANM-800 screen. If the channel path is displayed as "red," it means the test failed due either to the return of a distorted character or no return of the test character.
The operator also has the flexibility to view the control signal profile of the selected channel and to force the outbound control signals to either "on" or "off." The result: quick isolation of problems and restoration of service.
An actual data path can be quickly traced through the network topology map using this display. This screen also allows the operator to see how traffic has been re-routed when a problem arises.
This display gives the operator a means to determine channel usage. The operator can choose statistics for SDLC and emulation channel ports. Performance information includes total characters transmitted/received, percentage of data compression, and the number of good messages sent/received. These statistics help the operator to balance network traffic and minimize congestion.
This display compares the operational history of different channels, or the same channel on different days. The operator can evaluate channel performance based on the total number of bytes sent/received, data compression percentage, and the number of good messages sent/received.
This display gives the operator a chronological look at the alarm conditions for every device at every node of the network. Each entry includes a date/time stamp, the name and number of the reporting node, the reporting device, and the nature of the report. This listing simplifies network status reporting and trend determination.
These reports are available in three forms: a ten-minute report for a selected node or device, an hourly average of all reports, and an hourly total of all alarm conditions. The operator can assess operating conditions based on peak characters per second, buffer usage, and line error counts.
This allows the operator to compare the operational history of up to three different devices, or the same device in three different time periods. It consists of three bar charts showing the average (or peak) character throughput, buffer utilization, and data error counts. This information is essential for network planning.
This chart allows the operator to compile an overview of the data throughput at a selected node by showing the statistics for all devices at that node, simultaneously. It consists of one, ten-minute statistics report for every device in the selected node, including average and peak values for "characters per second" and buffer utilization.
